Question 9: the first graph would be moving upward at a constant rate, then gradually turn into a straight line horizontally. The second chart would start off in the mid-top area, then move downwards and stop at the bottom. The explanation is that in the first graph, he is moving a distance, then when he comes to a stop, he stops moving. Hr is covering no distance over time. The second graph shows his speed, and he goes from moving to not moving, not having any speed.
Question 10: Sketch an exponential graph(a graph that constantly increases across time) moving upwards. It is an exponential graph because the distances per second keep getting larger over time.
